GSC Power-Division Beehive Spring Set with Titanium Retainer Subaru EJ20/25

GSC Power-Division Beehive Spring Set with Titanium Retainer - Subaru WRX/STI

GSC Power-Division builds valvetrain components engineered for high RPM reliability under boost, and this beehive spring kit is a proven upgrade for the Subaru WRX and WRX STI. Using ovate wire with advanced heat treatment, these springs hold their load far better than a stock spring while still handling the fatigue cycles of daily driving or track use.

This listing covers the DOHC Subaru Turbo EJ platforms, including WRX GC8, GDA/GGA, GE8/GH8, GF8 and GV8/GR8, plus WRX STI GC8, GDB, GRF, GVF and VAB. The kit suits engines running EJ20 and EJ25 turbo configurations, both AVCS and non-AVCS heads, as noted in the manufacturer's application data.

Note: This is a valve spring and retainer upgrade only. It does not include camshafts or valvetrain components beyond what is listed below, and installation requires cylinder head disassembly.
